WILLIAM F. TUBESING, OF MILWAUKEE, WISCONSIN.

TIME-RECORDING WATCH.

Application filed July 5, 1912.

To all whom it may concern:

Be it known that I, lVILLmM F. TUBESING, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented new and useful Improvements in Time-Record ing lVatches, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to time recorders to be carried in the pocket as an ordinary watch and adapted to trace a record on a dial to indicate the time elapsing between the various adjustments thereof and thus form a permanent record of the duration of the succeeding events for which the adjustment is made.

The invention comprises a. watch provided with a disk on its face which turns instead of having hands to turn over a dial in the usual manner and this disk may be graduated by radial lines indicating time as well as preferably having concentric circles for the various adjustments of a sliding indicator which is adapted to mark upon the disk as the disk turns therebeneath.

Another object of the invention is to provide a disk graduated as desired and pro- Vided with a coating of a wax-like material which will receive the impressions of the stylus of the sliding indicator and constitute a permanent record thereof if so desired, but which may be readily restored to its original condition free from any trace of preceding record by the application of heat.

WVith the above and other objects in view the invention consists in the recording watch as herein claimed and all equivalents.

Referring to the accompanying drawings in which like characters of reference inclicate the same parts in the different views:

Figure l is a plan view of a time recordin watch constructed in accordance with th1s invention;

Fig. 2 is a sectional view thereof;

Fig. 3 is a detail, perspective view of the record disk and its support.

In these drawings 10 indicates an ordinary watch mechanism without dial or hands but having a disk 11 mounted thereon in place of the hour hand so that it completes one rotation in twenty-four hours. The invention is not confined to any particular time for the rotation of the disk. The disk 11 is provided with a pair of lugs 12 Specification of Letters Patent.

standing out from its face and a record disk 13 is correspondingly provided with a pair of openings 1st to fit upon said lugs 12 so that the record disk is driven by the watch works at the speed of disk 11. The record disk 13 constitutes a disk of paper or other material to receive an impression or to have a record line traced thereon by means of a stylus 15 carried by a slide 16 working in a slotted guide 17 which is attached to the rim of the watch case and extends part way across the record disk. The slide 16 has a lug 1S projecting from it by means of which it may be adjusted so that the bearing of the stylus 15 on the record disk 13 may be be tween any two of the concentric circles which are preferably marked on the face thereof. lVhen permanent records are desired the record disk 13 may be of paper and the stylus consist of a pencil point for tracing the record thereon, but if temporary records are desired, I prefer to make the disk 13 of sheet metal and coat the engraved or otherwise marked face thereof with paraffin or similar wax-like material which will take the impression of the stylus in its travel therebeneath, leaving a clearcut line to constitute the time record, but which by the gentle application of heat, as by holding a lighted match beneath the disk, will be restored to its original condition without trace of the former record and will then be adapted to have a new record engraved therein. The radial lines of the record disk are preferably provided with the numerals 1 to 12 representing the hours and on starting the watch it may be set to the correct time by turning the record disk in the usual manner for adjusting the hands of the watch until the proper time on the recordin disk is in the radial line of adjustment of the travel of the stylus of the indicator. During such setting of the watch the stylus may be either moved to a position where it is beyond the edge of the recording disk or itmay be sprung away from the disk, the connection for the guide 17 being of a spring nature which will permit of such movement. lVhen the watch is set, the indicator slide 16 is moved to bring the stylus 15 between two of the concentric circles on the record disk. The watch is closed and is left in this condition until the occurrence of some event which is desired to be timed, when the indicator slide is merely moved to changethe stylus from one position to another and thus throughout the day the various changes in position of the stylus and the time at which such changes were made are indicated by the record cut by the stylus in the wax coating of the record disk or otherwise marked upon the record disk. At the end of the day the record disk may be readily removed by slipping it off of the lugs 12, the indicator slide being sprung away from the disk 11 to permit thereof. The record disk may be replaced by another if it is to constitute a permanent record, or the record may be obliterated and the disk restored to its original condition by the application of heat if the record is only temporary. The record disk is as readily replaced as removed and is immediately placed in condition to receive a new record.

In practice this time recorder is found of great value to men who have to divide their time each day between different classes of work for which difierent charges are made or between different pieces of work charged to different parties. Thus, the space between two of the circles may represent one class of work and the space between other circles represent other classes of work, so that the time given by the individual carrying the watch to the several classes of work in any particular day will be indicated by the portion of the record line left by the stylus within the respective spaces. The operator does not have to charge his memory with the details regarding the time of changes made during the day, nor does he have to keep a watch so as to be convenient for carrying.

What I claim as new and desire to secure by Letters Patent is:

1. A record for recording means having suitable guide lines thereon and provided with a coating of wax capable of containing a record line having relation to the guide lines and capable of having such record line eradicated by the application of heat.

2. A record sheet for a time recording watch, comprising a record disk having radial lines thereon representing units of time measurement and concentric circles. thereon representing the difierent conditions under which the time may be spent, and adapted to have a stylus engage it at any of the record areas between the concentric circles, and a transparent wax coating on the record disk permitting the lines of the disk to show therethrough and adapted to have the path of travel of the stylus traced thereon and capable of having such record eradicated therefrom by the application of heat.

In testimony whereof, I affix my signature, in presence of two witnesses.
